This is our work horse unit!  The Mermaid Model M-16 – 16,500 BTU system produces phenomenal climate control to vessels. Manufactured on high grade 304-18 gauge stainless steel, this unit was engineered with your comfort in mind.
This unit is available in Right, Left, or Top air discharge configurations. We recommend at least three discharges for this unit. One 8″ x 6″ grill should be within 6 feet of the unit and at least two other discharges need to be at least the 4″ round supply vents.  As always, more is better; these are minimums.  The electric heat option is NOT available on this model.
